Energy management device and method

摘要

An energy management device manages a plurality of monitored devices distributed in a plurality of monitored areas. The energy management device determines whether a current time of each monitored area is during a monitored time of the energy management device. The energy management device acquires an area identifier and a body presence information from each of the monitored areas, and determines whether one or more monitored areas are under control and without body presence. If one or more monitored areas are under control and without body presence, the energy management device transmits one or more power-off commands to turn off the monitored devices located in the one or more monitored areas.
